2. Description of the Prior Art A driving device of this type has the disadvantage that it is liable to fail if the dimensional stability is not maintained or the driving passage is worn. That is, the binding member does not move. Therefore, such a driving device requires high dimensional accuracy and finishing accuracy,
In the same driving path, in most cases only certain binding elements can be used. Federal Republic of Germany Patent No. 35
According to the specification 0279, a driving device is known which is capable of processing two types of U-shaped binding members whose back widths are slightly different. This hammer magazine cannot be used for narrow and long clips of stronger wire or for tacks. Moreover, this device has an opening that is too small for use in places that are inaccessible.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is therefore to improve a driving device of the type described at the beginning so that various types of binding members can be processed, yet they are easy to operate and malfunction. It is to provide something that is difficult to do.

[0004]

According to the driving apparatus of the present invention which has solved this problem, the driving plate has the first leg that limits the driving passage and the right angle of 90 ° with respect to the first leg. A second leg that is bent at a right angle, and the slider is in contact with the second leg.

[0005]

The driving device according to the present invention having such features has the advantages that it is easy to operate and can be used universally, and at the same time high operational reliability is guaranteed. In particular, binding members that have not been completely driven in can be immediately retouched. further,
In particular, the binding member magazine can be easily manufactured accurately and can be easily incorporated. The device according to the invention makes it easy to load magazines with bindings and tacks of different widths. The wide clip is a sheet material,
It is particularly suitable for fixing cushioning materials, cloth materials, etc., and for furniture. Long, narrow cushions with thicker wires are suitable for panels, covers, molded wood and wrapping wood.

[0007] Advantageous constituent features of the present invention are described in claims 2 and following. It is advantageous if the guide rail is constructed as a sheet metal molding which opens downwards towards the slider. This allows the launch plate to be easily guided. According to the structure of the embossing plate described in claims 3 and 4, even in the opening having a long structure, the embossing plate can be formed at the correct angle in the under slider without aligning the surface that restricts the embossing passage and after-processing. Can be accommodated. The generally serpentine guide rail according to claim 5 simultaneously guides the slider laterally in the outer wall. If the magazine is configured as a so-called base magazine as described in claim 6, the contents of the magazine can be confirmed after the opening without removing the lossy member. This makes it very easy to remove obstacles in the magazine or in the drive channel. Loading can be done simply by pushing in. The integrally bent binding member slider according to claim 7 reduces manufacturing and assembly. The one-sided, externally slidable strip according to claim 8 is used as an insertion aid for narrow clips and as a lateral guide for tacks and pins. By disposing a tension coil spring instead of a simple spring, it is possible to apply a uniform pressing force to the binding member regardless of the filled state of the magazine. Depending on the shape of the end plate or the embossing plate, which is shaped according to the size of the binding element, it is possible to avoid obstruction by the binding element that is tilted or pinched in the driving channel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described in detail with reference to the embodiments shown in the drawings.

In the casing 1, the driving device has a driving cutter 2, which is driven by a coil through which a current flows, in particular by a motor, which is guided in a driving passage 3. The drive-in passage 3 extends into the magazine 4 and ends in an elongated opening 5. The magazine 4 is movably supported in the vertical direction, in the vicinity of the driving passage 3 in the elongated hole 7 with which the pin 8 fixed to the casing is engaged, so as to be movable in the vertical direction. Furthermore, the magazine 4 is rotatably connected to the casing 1 about a horizontal axis 9 at a rear end portion thereof facing the driving passage 3 side. This magazine 4 is mainly composed of a substantially U-shaped outer wall 11 which opens downward and a slider 12 which engages with the outer wall 11 (this slider 12 will be described in detail later with reference to FIG. 3). Made of The outer wall 11 has vertical slits 14 on both side surfaces 13, and a handle 15 is engaged with the vertical slits 14. The handle 15 is connected to a strip 16 movable within the outer wall 11. The strip 16 narrows a part of the inner chamber of the magazine 4 and is constructed as a sheet metal part or a plastic-steel-composite. Central part 1 of the outer wall 11 which is connected to both side faces 13 and forms the upper side (U-shaped web part)
7 has a narrow slit 18. The magazine 4 has, in the rear area, a locked connecting part 19 (not shown in detail) for fixing the slit 12. The front of the magazine 4 is attached to the side surface of the outer wall 11 and has a U-shaped outer wall end 21 that surrounds the driving passage 3.
Limited by The outer wall end portion 21 forms a tubular portion extending in the direction toward the driving passage 3 into which the end face plate 22 is inserted, and the binding member 23 to be processed is guided in the tubular portion. This is explained in detail in FIG.

The end plate is held by a U-shaped spring 24. To this end, the U-shaped spring 24 is fitted with a retaining pin 25, or the U-shaped spring 24 is provided with a groove or tongue, which groove or tongue is formed in the end plate 22. 26 (see FIG. 2). A U-shaped spring 24 is suspended on the outer wall end 21.

A support tongue 28 is bent from the outer wall end 21 on the lower side of the side surface 13, and the support tongue 28 surrounds the slider 12 and is fixed in its vertical position (see FIG. 1). ). The slider 12 itself has a base plate 30 according to FIG.
An integral guide rail 31 for guiding the binding member 23 is fixed to the center on the 0 by welding, for example. The guide rail 31, which is embodied as bent sheet metal, preferably has a width of 4 mm, so that the guide rail 31 guides a binding clip 32 with a back width of 4 mm. The guide rail has a recess 33 in the upper region, in which the tack 34 to be treated is located. The guide rail 31 has its bent leg portion 35 fixed to the base plate 30. This bent foot 3
One guide tongue 36 extends upward from each of the five. The guide tongue piece 36 laterally guides the side surface 13 of the outer wall 11. In the inside of the guide rail 31 having a hollow inside, a punching plate 39 is engaged from below through a slit 37 formed in the base plate plate 30. The embossing plate 39 has a binding member shearing edge, an embossing inclined surface, a guide surface, and the like. Metal Injektion Molding-Tech
nik) saves expensive processing work.

The stamping plate 39, which is shown in detail in FIG. 4, comprises an angle member 40, the first leg 41 of which limits the opening 5 of the driving channel 3. The second leg 42 bent by 90 ° with respect to the first leg 41 is used for the base plate 3 of the slider 12.
It is in contact with 0. A tongue piece 43 extends in the longitudinal direction of the magazine at a right angle from the center of the leg 42, and the tongue piece 43 projects into the open guide rail 31 and fills the guide rail 31. The embossing plate 39 is joined to the base plate and the guide rail 31 by welding, for example. This provides a large support surface and thus the embossing plate 3 for the slider 12.
The mounting of 9 in the right-angled direction is ensured, in which case the work of modifying the leg 41 which limits the drive-in passage 3 is omitted. The rigid connection between the embossing plate 39 and the slider 12 allows a long magazine opening 5.

The embossing plate 39 is the end face plate 2
Together with 2, a hardened drive passage 3 is formed. The magazine portion, slider 12 and outer walls 21, 11 may be left unhardened. This avoids the drawback of distortion when hardening a long sheet metal part.
A U-shaped spring 24 at the uncured outer wall end 21
Are used as hard locking edges for the locking springs incorporated in the casing 1.

FIG. 3 shows an example of three different binding members 23. In addition to the narrow binding clip 32 and the tack 34, a wide binding clip 45 having a back width of 10 mm, for example, may be guided in the magazine 4. The legs of the binding clip 45 directly rest on the side surface 13 of the outer wall 11. A strip 16 that narrows the space between the outer wall 11 and the guide rail 31 is required as an insertion half for a narrow clip. The strip 16 therefore remains in the rear position shown in FIG. 2 when processing wide binding clips.

An integral binding member slider 46 is guided along the guide rail 31. The binding member slider 46 is made of a thin metal sheet material having a cross section in the shape of the narrow binding clip 32. The binding member slider 46 is bent at both ends laterally and then upwards, like the guide rail 31, forming the tongue 44, whereby the legs of the wide binding clip 45 contact the contact surface 47. Is formed. The binding member slider 46 has a tongue piece 48 having an integrally formed hook 49,
The tongue piece 48 is engaged in the slit 18 and extends upward from the guide rail 31. In an empty magazine, the tongue piece 48 of the binding member slit 46 is
It abuts on the front edge of the slit 18 formed inside.
As a result, it is possible to prevent the binding member slit 46 from protruding into the driving passage and being damaged by the driving cutter 2 during idle driving. The tongue piece 48 is attached to the rear end portion of the binding member slit 46 which is particularly long. This allows the slit 18 to be located outside the loading chamber when the magazine is opened. This means that the binding members (clips, tacks or pins) are prevented from falling between the outer wall 11 of the magazine and the bottom of the casing. The tongue 48 is a U-shaped member 5 connected to the slit 18 of the outer wall 11 and the slider 12.
The slit 50 provided in No. 1 is engaged through. The U-shaped member 51 is releasably connected to the slider 12 for assembly or disassembly. The U-shaped member 51 is
On its front side, it has a diverting roller 52 at its end directed towards the drive-in passage 3 and a hook in its approximately central region. The tension coil spring 53 is suspended on the two hooks of the binding member slider 46 and the U-shaped member 51, and is wound around the deflection roller 52. The tension coil spring 53 thereby applies a tension force to the binding member slider 46 in the direction toward the driving passage 3 to push the binding member 23 into the driving passage 3. When the magazine 4 is opened, the U-shaped member 51 carries the binding member slider 46, so that the loading opening for inserting the binding member is opened.

The driving passage 3 has a molded end face plate 22 (see FIG. 5) within a range where the binding member is guided.
The front is restricted by. The end plate 22 is
The driving passage 3 is in the central range when viewed in the longitudinal direction of the magazine,
It is shaped to be constructed deeper than in the edge area. The end face plate 22 has a pair of lateral guide surfaces 55 in the edge region. This pair of guide surfaces 5
At 5, the entire leg width of the leg of the wide binding clip 45 is guided. The legs of the narrow binding clip 32 are wider than the legs of the binding clip 45 having a wide back portion. The end plate 22 has a second pair of retracted guide surfaces 56, which guide grooves 56 guide the groove 54.
Limiting the legs of the narrow clip 32 to abut at least a portion of their width. 1 to guide the tack 34
A pair of third guide surfaces 57 is provided, the third guide surfaces 57 themselves being the tacks 3 that exceed the width of the narrow binding clip.
4 heads are being guided. The end plate 22 is also formed with three or two steps on one side. Because the guide surface 56 on this one side
This is because it has moved to the guide surface 57 without a step. In this way, all the binding members 2 to be processed
3 is laterally guided in one end plate 22.

To improve the lateral guidance of the narrow clip 32, the guide groove 54 bounded by the two guide surfaces 56 is constructed deeper than the wire thickness of the clip 32 requires. In order to allow the clip 32 to be driven out of the driving channel 3 in this forwardly displaced position during the driving process, the leg 41 is provided with a small guide rib 58, the height of which is higher than the deeper position of the guiding channel. Equivalent to. The guide rib 58 is
The wide clip 45 is deformed as little as possible and is configured so as not to be damaged. For this reason, the guide rib 58 is narrow and has an extension 59 only at the end of the opening 5. In the range of this extension 59,
Since the guide surface 55 is also treated for the wide clip 45, the wide clip is guided up to the last few millimeters of the driving process without bending the back.

The configuration of the edges of the guide surfaces 56, 57 has a great influence on the result of driving the narrow binding clip 32 and the tack 34 and the service life of the molded end plate 22. The edges of the guide surfaces 56, 57 should be constructed as sharp as possible. It has been confirmed that the use of a sintered material gives good results, since the sharpening of the edge of such a guide surface is very expensive in the conventional manufacturing method. When using a sintered material, the guide surface 5
6,57 do not have to extend parallel to one another and can advantageously be constructed in the shape of a funnel. The sintered material may include oil, which further reduces wear.

Loading the binding device into the driving device is very simple. With the opening 5 of the device facing upwards, the slider 12 is pulled out backwards from the drive-in passage 3 in the longitudinal direction of the magazine. In this case, the tongue piece 48 of the binding member slider 46 is pulled out from the front side surface of the slit 50 formed in the U-shaped member 51. This makes it possible to process the entire cross section of the outer wall 11. The wide binding clip 45 is simply inserted downwards by pushing on the back and the slider 12 is closed again. To insert the narrow binding clip 32 and the tack 34, the strip 16 provided on the handle 15 is driven forward to drive the passage 3
The binding member is pressed against the binding member.
The slider 12 is then closed without problems. At this time, since the guide rail 31 is pushed into the binding clip packet, the binding clip 32 is placed on the guide rail 31. When the tack 34 is inserted, the tack 34 is held in the closed magazine by the flanks and recesses of the guide rail 31 and the strip 16.

When driving the wide clip 45,
The back portion of the clip 45 is bent substantially toward the end plate 22 within the range of the guide rib 58. This does not compromise the operational reliability of the device. Moreover, the narrow binding clip 32 has the advantage that a good lateral guide is obtained over most of the driving channel. The guide surface 56 is constructed narrow only over the last few millimeters, ie over part of the leg length. This narrow section is short enough that the clip leg does not bend laterally.
